, sembly and Fig. 11 is a plan of the sleeve shown in ferring to saiddrawings, which illustrate a simple embodiment of the present invention,the referencecharacter 12 designates the supporting frame of themachine,

which frame may comprise upright frame members 13 connected tohorizontal frame members, such as rings or bands, 14 andv 15, so as vtoprovide a rigid and substantial supporting frame for the mechanism ofthe machine. The frame members are preferably composed ofl channelformation in order to obtain strength and lightness. Supported upon thehorizontal frame member 14 isl the tub 16 in which is contained the'clothes agitating devices, here shown as comprising an agitator 17,-located adjacent the bottomv of the tub and a dolly 18 positioned above.the agitator. The dolly and agitator are mounted on a dolly shaft 48,

located below the tub and driven from an electric or other motor 19,which may be supported on a bracket 19a mounted on the frame-work of themachine? f The transmission gearing is contained within a gear case 20preferably composed of a'n upper 22 bolted or otherwise secured togetheralong oscillated by novel transmission gearing section 21 and a lowersection case is supported by chine, and, a's shown, standing lugs or itis provided with upl or otherwise secured to the band or ring 14, andthe lugs 24 being bolted or otherwise secured to a-brace bar 25 which issecured to the band or ring 14'. The ogear case lies lin ahori'zontalplane and contains "the, transmissiont'gearing, the shafts.of

which extend in vertical line, while the gear wheels and other powertransmitting elements lie in and move in horizontal planes,

the' frame ofthe mabrackets 23'and 24, the lug i whereby the use ofmitered'or beveled gears 'Referringx now to illustrate t e transmissiongearing in detail, it will be seen to comprise, among` other things, aspur gear wheel 26 having a vertical stud shaft 27 secured thereto andjournaled in a bearing formed in a boss 28 on the lower side of thelower gear case section 22. The spur gear wheel 26 is preferably formedwith a hub portion which is contained in a recess in the gear` case andrests on the bottom of said recess. Y

Meshing with the spur gear wheel 26 is a spur pinion 29 which is pinnedto a short vertical shaft 30 journaled in bosses formed .in the upperand lower gear case sections.

.The shaft 30 protrudes from the upper gear case section, and upon theprotruding end is pinned or otherwise secured a belt pulley 31 overwhich is trained a belt 32 which runs to a belt pulley 33 secured on thevertical shaft of tlg. motor 19. The spur gear wheel 26' and pinion 29arepreferably contained in the lower` section of the gear case, anddirectly above said spur gear wheel and pinion is a rocker arm oroscillating arm 34 which, as shown, is fulcrumed upon an axis concentricwith the axis of thewringer driving shaft shown at 35. Said wringerdrivingv shaft extends in' a vertical direction along the side ofthe tuband is provided at itsl upper end with, suitable gearing (not shown)lfor operating the wringer, but inasmuch as said wringer driving gearingforms no part of then present invention, itv has not 'been illustrated.

A horizontal spur gear wheel 36 is -provided for rotating the wringerdriving shaft 35, and said spur gear wheelpintermeshes with the spurgear Wheel 26,. The spur gear 4wheel 36 has a`I vertical, downwardlyexvtending stud shaft 37 secured to it, which is' the Xing sha journaledin a boss 38 formed on the lower section 22 and on the upper side ofthev spur gear -wheel it is formed with an upstanding hub portion 39which is journaled in a boss -on the upper gear case section. `The hubportion 39 acts as the fulcrum 'for the rocker arm-34 which is aperturedat one end to receive the hub portion. Suitable driving connections areprovided between the hubA of the spur gear Wheel 36 and wringer driv-35, and, as shown,` said connections comprise a clutch pin `40 securedin the wringer driving shaft 35 and entering fin notches formed in theupper end of the hub portion 39. A sleeve or casing 41 is/secured in theboss on the upper gearfcase section and extends up tothe housing (notshown) for' gears of .the wringer mechanism. T e rocker arm 34 restsupon the spur gear wheels 26 and 36, and horizontal plane, and means areprovided `for oscillating said rocker arm, which means, as shown,comprise a wrist pin 42 secured 1n the hub portions 43 of the spur gearwheel 26 and traveling in a slot 44 formed in the rocker arm 34. As apreference, a slide oscilla-tes in .a i

block 45 is provded upon the wrist pin Aand u slides in the slot of therocker arm. Upon the free end of the rocker arm is`a gear segment 46which meshes with a spur pinion 47, loosely mounted upon the doll shaft48 which is journaled in a boss 49 ormed on the lower gear case section22.

The spur pinion 47 and dolly shaft 48 are provided with lco-actingclutch jaws 50 and 5l, whereby the pinion and dolly shaft may `beclutched together or unclutched from shaft'48. As illustratedv in thedrawings, the

lower end of the lsleeve is formed with a shouldered portion 56 and witha threaded npart 57 which screws into a threaded opening in theuppervend of thehousing 54. The bottom 58 of the tub is secured betweenthe shoulder 56 of the sleeve 55 and the upper end of the housing 54,and gaskets 59 are provided between the tub bottom 58, the shoulder 56and the housing 54 tornake a leak proof joint at this point. Anoutwardly opening chamber 60 is formed in the housing 54 below the lowere'nd of the threaded 1-00 part 57 ofthe sleeve 55, and in 'said cham.ber is a cone shaped disky 61 of rubber ory ,the like, whichA disk fitssnugly Vupon the dolly shaft 48 and acts to shed `any waterl tricklingdown along the dolly shaft, away fromthe mechanismsbelow the disk.

Rotatably mounted upon the bearing sleeve 55 is a supporting member 62for the dolly andy agitator,` here shown in the form f of a sleeveprojecting `above the bearing sleeve 55 and having its upper end pinnedor otherwise secured to the upper end of the dolly shaft 48, wherebytheoscillatory'1 movements of the dolly shaft are imparted to saidsupporting member 62. The agitator17 is removably mounted upon thesupportingmember 62. As shown, the supporting member 62 is formed at itslower end with a shoulder-63 upon which the agita` r tor rests, andLthe' supportingglnember is formed with a plurality of grooves 64 in itsface that are adapted to recelve lugsv or other projectionsA 65. formedon the agitator, whereby the latter is. connected to the'vagitatorsupporting member 'sd as to oscillate therewith,vbutjcapable ofbeingreadily removed therefrom by. lifting it up above the doll shaft. l

v T e agitator is of novel.construction.` It it composed of a. flaringor bell shaped body portion, the lowery marginal edge portion undersideof the flaringor bell shaped partof the agitator is formed a downwardlyprojecting sleeve or collar 67 which also' sur.-

rounds the agitator supporting member,`

both of said sleeves forming a long bearing or connection between theagitator and its supporting member, thereby preventingany tendency forthe agitator to tilt upon its` support.

0n the upper face of the body portion of the agitator are radial ribs68, which by preference upstand only slightly and merge into the facethereof at places -adjaceht its upper end. Said ribs' which engage theclothes cooperate with a dolly, presently to be described, in propellingthem back and forth in the tub during the washing operation.` It will beunderstood that the clothes, which are being washed, rest in part uponthe agitator so as to be carried by it back and forth, around theinterior of the tub.

rllhe walls ofthe body portion, sleeves and ribs may be formed ofrelatively thin, light weight material, such as aluminum, if desired.

Associated with the agitator is the dolly 18, which is also removablyheld on'the agitator supporting member 62. As shown, thedolly has aconcavo-conveX, or dished disklike body -portion 69 which extends froma' central hub portion 70 that surrounds the agitator supporting memberand is formed with lugs or ton ues 71 which engage in the grooves 64 o'the agitator supporting member. On the lower convex side of the `dollyare downwardly projecting radial lugs 72 which engage with the clothesand act to propel them back and forth in the interior of the tub. lfdesired, the lugs may be cast hollow, as shown, for the sake oflightness, and a number of apertures 73 are formed in thebodyof thedolly to permit water to pass through the same.- The dolly ma be formedof cast light weight material suc as aluminumyifdesired. i

Conveniently, one orr more knobs 74 are secured to the'disk-like portionof the dolly and furnish' means whereby the same may be handled inplacing it upon'the agitator fsupporting member or removing it there-.'from, or 1n casevlt V1s vdesired to turn the dolly and agitatormanually. llt-is to be l understoodv thatmthe' dollyy is slidablyconlnected with the agitator supporting member andis free to move up anddown thereon. Fig. 8 of the .drawings showsthe dolly as suspended, whichis a position occupied by it`when resting upon a batch of clothescontained. in the tub. When placingclothes in the washing machine or'removing them therefrom, the dolly may bey'` disconnected from theagitating supportingmember and afterwards replaced, When clothes arecontained in the tub the dolly rests upon the clothes, but when theclothes are removed it rests upon, the upper end of the agitator.

From the above it will/be observed that thermore, the arrangement of theverticall shafts permits the motor shaft to extend vertically which isof particular importance. By arranging the fulcrum of the rocker armconcentric with thev wringer ldriving shaft, a relatively long rockerarm is obtained, and by placing the rocker arm actuating wrist pinintermediate the ends of the rocker arm a long sweep is given to theArocker` arm with a very steady and even motion. With the long sweep ofthe rocker arm, the dolly and agitator are moved through the greaterpart of a complete circle.

lt is also to be observed that by `reason of the novel disposition ofthe power transmitting elements, the oscillatory member thereof isoperatively connected to the dolly shaft without the interposition ofanybevel o r miter gears and one of the continuously rotating powertransmitting members is op erativelyl connected` to the wringer drivingshaft without the interposition of any bevel or miter gears. 'The noveldolly shaft. assembly enables the parts tobe readily assembled inconstructing theV machine and permits theA ready removalv andreplacement of the dolly and agitator. The bell shaped or flaringagitator, while acting asl a support for the clothes, prevents them frombecoming tangled around the dolly shaft. lf

desired, however, the agitator may be dispensed with, in which case, theclothes rest upon the bottom of they tub. The dolly `being freelymounted upon ythe supporting sleeve,

it`rests uponV the clothes during the washing operation and thedepending lugs thereof yenter among the clothes and carry them aroundback and forth through the water duced speed. yAs the spurA gear wheel26 rotates, the wrist pin 42 is rotated in the slot 44 of the rocker arm.34,.and, as a consequence, the rocker arm is oscillated, thereby.

imparting a rotary reciprocatory or oscillatory movement to the spurpinion 47. Inasmuch as the spur gear wheel 36 for the wringer driving,shaft 35 intermeshes with ne. A

ila

the spur gear wheel 26, the wringer .driving shaft is continuouslyrotated during the operation of the transmission gearing. By

properly shifting the clutch lever 53, the

dolly shaft 48 may be clutched to the spur `v pinion 47 or unclutchedtherefrom as desired, and, in this way, the operation ofthe agitator anddolly may be controlled.

It will be observed that the clothes are supported, at least in part, bythe agitator and that the dolly rests upon and engages with the clothes.The agitation of the clothes is accomplished by the dolly with theclothes resting upon the agitator. The clothes, being conined betweenthe agitator y .and dolly, are carried back and forth through the waterin the tub, whereby a very thorough washing action is obtained on the'clothes. Furthermore, this arrangement prevents the clothes from beingtangled and also provides means for agitating the clothes throughout thedepth of the tub, since the agitator co-operates with the dolly inswinging the clothes back and forth in the tub. By the term agitator,wherever used in )the specification and claims, is meant a ysupport forthe clothes operatively connected With the dolly shaft so asto rotatetherewith. f

More or less variation 4of the exact details of construtcion is possiblewithout departing from the spirit `of this invention; We desire,therefore, not to limit ourselvesV to the exact form of theconstructionfshown and described, but intend, in the following claims,to point out all ofthe invention disclosed herein.
